Computer virus~ Can I get rid of it on my own?

It could be a malware worm, a very complex virus that can even take down anti viruses itself. If you can still access the internet go google malwarebytes, download it, its free, after downloading, restart your computer, and tap F8 repeatedly to go to a black screen with multiple options, press Enter when you select safe mode and click on malwarebytes to scan your computer, and when its done scanning, it will prompt you to restart your computer and the virus should be rid of.
